GR1008978B - A system for the construction of a solar collector furnished with thermal break aluminium profile - Google Patents

Abstract

Novelty: a system meant for the construction of a solar collector furnished with a thermal break aluminium profile is disclosed. Technical features: the invention is consisted of the basic profile (2,6) which is thermally insulated with polyamide (7) of desired length. The profile (2) bears lengthwise apertures (3) and has at its ends through or blind apertures creating a flow field allowing the circulation of water by uniting one to another the aforementioned vertical apertures (3) up and down. The ends of the horizontal apertures close up with stainless screws (15) screwed in the aperture (4). Stainless screws (8) screw at the ends of the apertures (3) to seal the apertures (3). A unified water flow field is thus created at the profile (2) where a fitting (16) screws in the terminal aperture (3), at the upper and lower end consisting the water input and output, respectively. A glass pane (10) is fixedly adhered via tapes (9) to the thermal break profile. Caps (19) bearing the elastic flange (18) meant for the sealing of the ends of the solar collector are fixed on the two ends of the profile (2); solar radiation is attracted and collected either by anodising of the profile (2) in black colour or by dyeing of the exposed-to-the-sun surface with a marketed coating suitable for solar radiation attraction. Both, solar collection surface and water capacity depend on the height of the thermal break profile whichis cut out accordingly. By uniting one solar collector with another via the junction profile (24), we take advantage of the whole solar collection surface of both solar collectors. The elastic tube (17) and marketed tighteners connect the terminal fittings (16) (fig.4).

Description

1. DESCRIPTION

SOLAR COLLECTOR CONSTRUCTION SYSTEM WITH

THERMO-SWITCHED ALUMINUM PROFILE

The invention refers to a solar collector manufacturing system with a thermo-switchable aluminum profile.

To date, solar panel manufacturing technology has not demonstrated any similar construction.

Solar collector structures are mostly made of a piping network consisting of two horizontal pipes with holes and a number of vertical ones which are welded together and form a flow field for the collector water. This network is placed in a frame with a black collector surface plate. The frame has a glass pane on the top and an insulating surface on the bottom. This type of construction has a high construction cost and requires the construction of solar panels of different dimensions for a corresponding amount of water in the flow field. The invention aims and succeeds in solving these basic disadvantages in a way that constitutes a new technical rule in solar panel manufacturing technology.

The advantages provided by this invention are mostly:

1) Significant reduction in construction costs.

2) Monoblock construction of frameless thermoswitch collector.

3)  Increased efficiency of the solar collector depending on the length cut of the base profile.

4)  Lesser manufacturing volume.

5) Excellent aesthetic result.

A way of applying the invention is described in the following with references to figures that illustratively and descriptively illustrate a way of basic implementation where:

Figure 1 shows a cross-section of the thermal break profile that the solar collector is made of.

Figure 2 shows a cross-section of the solar collector with its insulating elements, side and bottom.

Figure 3 shows a perspective view of the solar collector disassembled.

Figure 4 shows a perspective view of two identical solar panel sections joined together.

The figures show a construction system of a solar collector which consists of a basic profile (2) and (6) which are stitched together with commercial thermal break polyamide (7). Commercial insulating materials (12) are placed between the profiles (2) and (6). At the bottom of the profile (2) is heat insulating material (13) with a thin metal surface (14). The insulating materials are intended to prevent the escape of temperature to the external environment and vice versa as shown in Figure 2. The profile (2) has twenty-five holes (3) in this particular example. The profile (2) is cut accordingly to the desired length. At the two ends of the profile (2) and approximately twenty millimeters from its ends, there are holes (4) which are made with a drill, through or blind, which create a flow field for the circulation of water. That is, they join the vertical holes (3) together above and below. The ends of the horizontal holes are closed with stainless steel screws (8) which are screwed into the hole (4) with commercial thread glue to ensure absolute sealing. At the ends of the holes (3) are screwed stainless steel screws (15) with commercial thread glue to seal the ends of the holes (3).

In this way, a single field of water flow is created in the profile (2) where a fitting (16) is screwed into an end hole (3) at the lower end and correspondingly one at the upper end which constitute the inlet and outlet of the water. The horizontal holes (4) in the profile (2) can be made before stitching the profile (2) with the profile (6). In the grooves (5) of the profile (2) are inserted sliding profiles (11) which have silicates inside them to prevent sweating of the glass panel (10) which is supported by the double-sided adhesive elastic bands (9) (commercial) as shown in Figure 2. At the two ends of the profile (2) are supported caps (19) which carry an elastic flange (18) for sealing the ends of the solar collector. The caps (19) have holes (20) in which sheet metal screws (22) are inserted and screwed into the grooves (25) carried by the profile (2). The fitting (16) also exits from the hole (21) on the cap (19). With this method, it is clear that the construction of the solar collector is significantly simplified by having a monobloc construction from a thermal breakable body consisting of profiles (2) and (6). The profile (2) may be anodized with black anodization to attract and absorb the sun's rays, or its surface exposed to the sun may be painted with a similar commercial coating that attracts the sun's rays. By cutting the thermal break profile to a corresponding height, we increase the collecting surface and the water capacity accordingly. Also by adding one solar collector next to the other with the connecting profile (24) we have a desired surface area of all the collectors. The end fittings (16) are bridged with a rubber tube (17) and commercial clamps as shown in Figure 4.

The above basic components are assembled as shown in the attached drawings during one of their basic construction and operation. Possibilities of detailed modifications are not considered in the present description and drawings. For any manufacturing need, it is possible to modify either the forms of the components or their sizes as well as the type of materials without them altering the basic principle of the invention which consists in the construction of a solar collector without piping and without a frame but of a thermal break element consisting of from a profile (2) with holes (3) and by creating two horizontal holes (4) as well as blocking the end of the holes (3) and (4) with screws (8) and (15) we create a single flow field and water circulation.

3. CLAIMS 1.  A solar collector manufacturing system with a thermal break aluminum profile characterized by being composed of a profile (2) having corresponding holes (3). At the two ends of the profile (2) and about twenty millimeters from its ends, there are holes (4) which are made with a drill, through or blind, which create a flow field for the circulation of water by joining the vertical holes (3) between them above and below. The ends of the horizontal holes are closed with stainless steel screws (8) which are screwed into the hole (4). Stainless steel screws (15) are screwed into the ends of the holes (3), creating a single water flow field in the profile (2). A fitting (16) is screwed into an end hole (3) at the lower end and correspondingly one at the upper end which form the inlet and outlet of the water. At the two ends of the profile (2) are supported caps (19) which carry an elastic flange (18) for sealing the ends of the solar collector. The caps (19) have holes (20) in which sheet metal screws (22) are inserted and screwed into the grooves (25) carried by the profile (2). The fitting (16) also exits from the hole (21) on the cap (19). By cutting the thermal break profile to a corresponding height, we increase the collecting surface and the water capacity accordingly. Also by adding one solar collector next to the other with the connecting profile (24) we have a desired surface area of all the collectors.
